摘要： 热研9号坚尼草是1988年从哥伦比亚国际热带农业中心引进的新品系,经鉴定后于1990年开始进行系列研究。结果表明,热研9号坚尼草不但保持了该属牧草高产优质的特点,干草产量18000kg/hm2·a,比对照增产40%,干物质含粗蛋白质7.90%,种子产量495.8kg/hm2,增产93.9%,而且具有耐酸瘦土壤、耐低温干旱、较耐荫蔽等特点,适宜在我国热带及亚热带地区种植。

Abstract: Panicum maximum cv.Reyan No.9 is selected from a group of tropical forage varieties introduced from CIAT in 1988 and began to trial in 1990. The preliminary results showed that P.maximum cv.Reyan No.9 maintained its genus characteristics of high dry matter yield and quality. Its dry forage yield was 18000kg/hm2 and seed production was 495.8kg/hm2,improved 40% and 93.9% than P.maximum cv.Trichoglume respectively,crude protein (CP) contents was 7.90% (DM); acid-infertile tolerance、shade tolerance、low temperature、dry tolerance improved significantly and adapted to plant in tropical and sub-tropical regions especially release in South-China.
